Intelligent Serial Interface (KSI)

The KSI Interface allows multiple serial cash drawers to be linked on a single serial port (RS232). The trigger code is selected via a row of DIP switches on the interface. The interface can also be set to operate in standard 'Pulse' mode. Power is provided by an external power supply. Cabling options allow for in-line or dead-end operation.
